We consider a finite-size topological Josephson junction formed at the edge of a two-
dimensional topological insulator in proximity to conventional superconductors and study …

We study the unconventional superconducting correlations caused by a single isolated
magnetic impurity in a conventional s-wave superconductor. Because of the local breaking …

Magnetic impurities at surfaces of superconductors can induce bound states referred to as
Yu–Shiba–Rusinov states (ie Shiba states) within superconducting (SC) gaps. For …

The Yu-Shiba-Rusinov (YSR) state appears as a bound state of a quasiparticle at a
magnetic atom embedded in a superconductor. We discuss why the YSR state has energy …

We show that vertex corrections to Migdal's theorem in general induce an odd-frequency
spin-triplet superconducting order parameter, which coexists with its more commonly known …

Impurities coupled to superconductors offer a controlled platform to understand the interplay
between superconductivity, many-body interactions, and nonequilibrium physics. In the …

We consider Josephson junctions formed by multiple superconductors with distinct phases
and explore the formation of nonlocal or intersuperconductor pair correlations. We find that …

The spin transport inside an odd-frequency spin-triplet superconductor differs from that of a
conventional superconductor due to its distinct symmetry properties. We study spin transport …

We show that dilute magnetic impurities in a conventional superconductor give origin to an
odd-frequency component of superconductivity, manifesting itself in Yu-Shiba-Rusinov …

Optimal choice of spin polarization enables electron injection into the helical edge state at a
precise position, despite the uncertainty principle, permitting access to specific nonlocal …
